  ****************************************************************
  When DB2 Dynamic Statement Cache (DSC) is active, the DSC LONG
  PREPARE process inserts the dynamically PREPARed statement
  in the global cache. When there is not enough space to insert
  a new statement, DB2 drives the LRU process to remove an old
  statement in the cache to have space for the new statement.
  
  When a statement is being removed from the cache, DB2 may write
  the IFCID 316 trace record. While tracing the IFCID 316 record,
  an SQLCODE can occur (such as a conversion error). This negative
  SQLCODE can affect the LONG PREPARE process of a new
  statement, which results in undoing the PREPARE of
  the statement. However, this statement is still advertently
  inserted in the cache without valid dependency information.
  The internal control block of the dependency information
  can be reused for another cached statement later. This
  inconsistency is detected on a subsequent statement invalidation
  process resulting in the reported abend.
  

Problem conclusion

• DB2 code has been modified to not insert a statement
  in the cache, if an error was hit during the LRU
  process.
